Crashing when two people are building a roundpole fence gate

[Tanithal]

This has happened twice to my friend and I. We were both building a gate (both pressed build) and when we finished, I crashed. Some sort of error, I'll try to get it next time it happens.
So, we're building another gate, and this time he crashes. Same error.

Anytime two people build the same item at the same time it risks a crash. It's not specific to roundpole fences.

As a matter of etiquette the person who puts the material in builds only what they put in and both take turns.

This is another little piece of the H & H culture, like always moving the split instant you go in or out of a house or a mine to prevent trapping and being trapped by the next person through.
